I take that back.  Although I could burn CD's, I still couldn't mount them until I started playing
around with modprobe/insmod/lsmod and then it all magically started working - even though I
thought I had un-done everything that I had done did ;)

Since then I've checked the Red Hat site again for info on this.  They've created a "Red Hat Linux
7.2 Install FAQ" which has as it's second entry, "CD-ROM fails to mount after install/upgrade to
7.2".  (http://www.redhat.com/support/resources/gotchas/7.2/)

Here's the text:

"We have found an installer related bug in some hardware set-ups. After an installation of 7.2 or
upgrade of an existing system, these units report "/dev/cdrom not a valid block device"
  causing the mount to fail and a possible system crash. Running the command as root "depmod -ae"
should solve this issue. Additionally, upgrading to the latest kernel errata will solve
  this issue. 

  To view the bug report: Bugzilla 55071"

(https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=55071)

So it looks like my 2 year old CDROM drive might be OK after all...
